So me and my buddy known on clubcivic as ZACH246 just swaped his 1992 si with a gsr motor this weekend and were running the p28 ecu so the butterfly valves are always open is that bad for the motor? He's gonna get a p72 this week so just wondering how much power loss were getting and also we gotta wire the dizzy back to obd1 cuz the motor is a 1997. Thanks for any help.
